Default Low Vitamin D May Increase Stroke, Heart Attack Risk in Women

Another article I found interesting and wanted our female posters to see it.

TUESDAY, Nov. 15 (HealthDay News) -- Low levels of vitamin D may put women at greater risk for heart attack and stroke, according to one of several new studies on the important nutrient.

After analyzing 16 years of data on more than 2,000 healthy, postmenopausal white women aged 45 to 58, researchers found that the 788 women with a vitamin D deficiency had more risk factors for heart disease than 1,225 women with normal levels of the vitamin. They were scheduled to present their findings Tuesday at the American Heart Association annual meeting in Orlando, Fla.

Women with low vitamin D levels had higher levels of triglycerides; higher fasting glucose; a higher body mass index; and lower HDL "good" cholesterol. The researchers noted 47 percent of the women who were deficient in vitamin D were smokers compared to 38 percent of the women with normal vitamin D levels.

About 15 percent of the women deficient in vitamin D either died or suffered heart failure, a heart attack or stroke during the study period compared to 10.2 percent of the women who did not have this deficiency.

Three other studies also looked at vitamin D's possible protective effects on the heart. One study found that people who took 4,000 units of vitamin D daily for five days following a severe heart event had less inflammation afterward than patients who didn't take the supplement.

A third study found that chest pain patients with low Vitamin D levels were more likely to die during the next two years than those with adequate levels of the nutrient.

Finally, a fourth study found that higher levels of vitamin D were associated with lower death rates from cardiovascular disease.

Because these studies were presented at a medical meeting, the data and conclusions should be viewed as preliminary until published in a peer-reviewed journal.

Australian Funnel Web Spider venom may offer stroke therapy...

Spider venom may offer stroke therapy
Mon, 20 Mar 2017 - Protein extracted from funnel webs may help minimise the effects of brain damage after a stroke.
Quote:
Scientists found a single dose of the protein Hi1a worked on lab rats. They said it showed "great promise as a future stroke treatment" but had not yet been tested in human trials. The Stroke Association said the research was at its early stages but it would "welcome any treatment that has the potential to reduce the damage caused by stroke". The researchers, from the University of Queensland and Monash University, travelled to Fraser Island in Australia to hunt for and capture three potentially deadly Australian funnel web spiders. They then took the spiders back to their laboratory "for milking". This involved coaxing the spider to release its venom, which can then be sucked up using pipettes. The scientists honed in on a protein in the venom and recreated a version of it in their lab. They then injected this Hi1a into the lab rats.


Funnel web spiders are milked using a pipette that sucks up their venom

* A stroke is a brain attack that happens when the blood supply to part of the brain is cut off or there is bleeding on the brain
* Every two seconds, someone in the world will have a stroke
* Almost 17 million people who had never had a stroke before had one in 2010
* Stroke is the second most common cause of death, causing about 6.7 million deaths each year, one every five seconds
* Almost one in every eight deaths is caused by stroke
* The burden of stroke-related illness, disability and early death is set to double within the next 15 years

They found that the protein blocked acid-sensing ion channels in the brain - something the researchers say are key drivers of brain damage after stroke. Prof Glenn King, who led the research, said the protein showed "great promise as a future stroke treatment". "We believe that we have, for the first time, found a way to minimise the effects of brain damage after a stroke. "Hi1a even provides some protection to the core brain region most affected by oxygen deprivation, which is generally considered unrecoverable due to the rapid cell death caused by stroke." The research was published in Proceedings of the National Academy of Sciences.


Researchers say the protein "provides exceptional levels of protection for eight hours after stroke onset"

Dr Kate Holmes, deputy director for Research at the Stroke Association, said: "We do not have an accurate picture of what happens in human brains from this research, therefore, it is currently unknown if this could be a successful treatment option for humans in the future. "We welcome any treatment that has the potential to reduce the damage caused by stroke, particularly if this can benefit people who are unable to arrive at hospital quickly. "Current treatments must be given in half this time period, and it is too early for us to know if this research can offer an alternative for stroke patients. "We urge for stroke to be treated as an emergency - the sooner a person can get to hospital after a stroke, the sooner the right treatment can be received, which can improve survival and help recovery."

Granny takes vitamin D so she don't catch a cold...

Study: Vitamin D could prevent common cold
Sun, Mar 19, 2017 - A study announced on Feb. 16 indicates that taking Vitamin D supplements can prevent respiratory tract infections such as colds and influenza, reigniting the debate on the effectiveness of non-prescription dietary supplements.
Quote:
The study, in the British medical publication BMJ, claims to have discovered, for the first time, “clear evidence” of a link between Vitamin D and influenza, after evaluating the different results from a total of 25 clinical trials in 14 countries. This is especially apparent for people suffering from Vitamin D deficiency. Vitamin D can be absorbed through a number of foods. The human body is also able to synthesize Vitamin D endogenously when ultraviolet rays from sunlight make contact with the skin.

Many people have Vitamin D deficiency, especially residents of areas of climates of low levels of sunlight. For many years, scientific studies have come up with mixed conclusions about Vitamin D, with some finding that low levels of Vitamin D can increase the risk of bone fracture, cardiovascular disease, colorectal cancer, diabetes, depression, Alzheimer’s disease and death. Other studies, however, showed that it was impossible to prove a link between Vitamin D and risk of disease.


According to a new British study, taking Vitamin D supplements could help prevent the common cold and influenza.

True or False

A) For some time, sporadic studies have demonstrated evidence of a link between Vitamin D and certain diseases.

B) The recent BMJ study has shown for the first time clear evidence of a link between Vitamin D and diseases such as cancer and Alzheimer’s.

C) As a result of this study, the medical establishment now believes that dietary supplements can cure the common cold.

D) Vitamin D can be found in some foods, but can also be produced by the human body.

Answers: A) T, B) F, C) F, D) T
